Formaldehyde is commonly accepted to be an allergen and irritant. However, specifically diagnosed occupational respiratory diseases caused by formaldehyde are relatively rare. Occupational laryngitis was diagnosed in a 47-year-old dairy foreman. He had been exposed for 9 years to formaldehyde emitted from a milk-packing machine situated underneath his office. His exposure level varied considerably. Under normal process conditions, the measured formaldehyde level was 0.03 mg/m3. The patient was examined by different specialists over 1 1/2 years. It was concluded that he had psychogenic dysphonia. However, a specific laryngeal provocation test with formaldehyde carried out at the Finnish Institute of Occupational Health was positive. His laryngitis was so serious that he was pensioned. During the 3 years of follow-up his condition gradually worsened. He now reacts especially to tobacco smoke and other air impurities known to contain formaldehyde.
甲醛通常被认为是一种过敏原和刺激物。然而，由甲醛明确诊断出的职业性呼吸系统疾病相对较少。一名47岁的乳品厂工头被诊断出患有职业性喉炎。他在其办公室下方的一台牛奶包装机所排放的甲醛环境中暴露了9年。他的接触水平差异很大。在正常生产条件下，测得的甲醛水平为0.03毫克/立方米。在1年半的时间里，不同的专家对该患者进行了检查。结论是他患有精神性发声障碍。然而，在芬兰职业健康研究所进行的一项针对甲醛的特定喉部激发试验呈阳性。他的喉炎非常严重，以至于他领取了养老金。在3年的随访期间，他的病情逐渐恶化。他现在对烟草烟雾和其他已知含有甲醛的空气杂质反应尤为强烈。
